Rocking-swinging window

ABSTRACT

The window comprises a rectangular casing and a leaf mounted on a frame and can be caused to pivot about an axis located at the vertical leaf edge or about an axis located at the bottom horizontal leaf edge. The window is provided at one corner with a support comprising a vertical pivot-pin and a horizontal pivotpin, a link-rod system disposed along the two sides of the window which do not serve as an axis of rotation, the displacements of said system being such as to create one point of pivotal motion and to release the other in alternate sequence. The link-rod system is coupled to a cam having a surface applied in contact with said system so as to displace this latter over certain parts of the cam contour while permitting the system to remain motionless over other parts of the contour.

Windows of this type areemployed in all structures and their usefulness is evident since they permit both rational ventilation without draughts (bellows-type opening) and a wide opening (casement-type opening) for the purpose of easy cleaning of the unit and intense ventilation.

In order to be really practical, windows-of this type must be "very easy-to handle. This makes it necessary to ensure on the one hand that the two types of opening can be obtained by operating a single handle witout entailing any need to perform any operations and, on the other. hand, that the movement of the window is very smooth at the time of opening in the bellows condition or in other words that there is no need to retain the window during its pivotal motion. In addition, the action either the horizontal axis of rotation or the vertical axis of rotation. Apart from ,the disadvantage which lies in the fact that this additional operation can be arduous when the window is no longer new, this displacement makes it difficult to ensure leak-tightness betweenthe fixed casing and the window leaf.

The precise object of the. present invention is to provide a rocking-swing window which overcomes the disadvantages just mentioned.

. -Th'e vertical rocking-swinging window which com prises-a fixed rectangular window-casing and a leaf a mounted onya frame and which is capable of pivoting about 'a verticalaxis in coincident relation with a vertical leaf edge orabouta horizontal axis in coincident relation'with the bottom horizontal leaf edge, is characterized in that it comprises:

at the comer which coincideswith the point of intersection of the two axes, a support comprising two pivotpins, namely a vertical pin and a horizontal pin, at the second bottom corner and at the top corner which defines the vertical axis, means for creating a point of pivotal motion of the leaf withrespect to the casing,

' .a link-rod system disposed along the two sides of the window which do not serve as an axis of rotation, the displacements of the link-rod system being such as to be capablein alternate sequence of creating one of the two points of pivotal motion and releasing the other, said. link-rod system being coupledto a cam which is rotatable about-a shaft, said camhaving a surface ap- In a second embodiment, the link-rod system is placed within the hollow frame of the window leaf.

A better understanding of the invention will in any case be obtained from the following description of one embodiment of the invention which is given by way of example without any limitation being implied, reference being made to the accompanying figures, in which:

In the following description, it isconsidered that the window is in the" normal vertical position of use; and it is with reference to this position that the terms hori zontal and vertical. employed in the following description must accordingly be understood. A prime mark on a number indicates a part similar to the part elsewhere. 1

The rocking-swinging window comprises a fixed rectangular casing 2 and a movable leaf 4. Each upright of the. fixed window-casing 2 has a. rectangular cross section. The cavity 6 of the fixed window-casing 2 con-' tains a system 'of link-rods. This link-rod system essen-. tially comprises a horizontal rod 8, an articulation tri angle 10 and a rod 12. The rod 8 which is constrained to move along its axis by means of guides (not shown) is provided at one end witha tongue 14 which is capable of sliding within a groove 16 formed at one of the apices of the articulation triangle 10. The other end of the rod has an elbowed portion 18. o

The right-angled articulation triangle 10 is capable of pivoting about a horizontal pin 24 which is rigidly fixed to the window-casing 2 and passes through the bore 26 of the triangle 10. Said triangle '10 has a second groove plied in contact with the link-rod system so as to-displace the entire system over certain parts of its contour while permitting said system to remain motionlessover other parts of said contour. o I

In a first embodimenLthelink-rod system is placedwithin the-hollow window-casing.

28, a stud 30 which is rigidly-fixed to the upper end of the rod 12 being sliclably fitted in said groove. The rod 12 is provided at the lower end thereof with a lug 32 and at its mid-height with two horizontal arms 34 and 36 applied on each side to a cam 38 which is fixed on a spindle 40 located at right anglesto the plane of the window. There is mounted on the same spindle alocking-bolt or latch 42 which is capable of moving out of the frame 2 by means of a slot44 formed in the wall of said fixed window-casing 2. The cam is rotated by means of the operating handle 46 which is mounted at the end of the spindle 40.

The window leaf 4 is constituted by a pane (or a double pane) 48 over the horizontal edges of which are fitwhich is secured to the window pane 48; but the frame could equally well surround the four sides of the pane 48. There is shown in FIG. 4 one example of assembly of the cross-piece 50 on the window pane 48. The cross-piece 50 has a cross-section having the shape of an h, the two bottom arms of which grip the edge of the pane 48 by means of screws such as 54 which are applied against the pane with inter-position of a flexible seal 56. The window pane 58 can also be bonded directly to the sectional member.

The leaf4 is pivoted on the one hand about the horizontal axis YY and on the other hand about the vertical axis X-X. The hinge unit having the axis YY' is constituted by two parallelepipedal members 58 and 60 each having a horizontal pivot-pin 62 and 64 which are engaged in a bore formed in the leaf 4 parallel to the bottom edge of this latter. Each member 58 and 60 is secured to one end of a torsion bar 66 and 68, the other end of which is rigidly fixed to the window leaf 4. The member 58 is also provided with a groove 70 which is open at the lower end and capable of accommodating the lug 32. The member 60 is provided at the lower end thereof with a vertical pivot-pin 72 engaged in a cylindrical bore 74 which is pierced in the fixed window-casing 2. The'window leaf 4 is provided on the top horizontal edge thereof with a vertical pivot-pin 76 which is coaxial with the pivot-pin 72 and is capable of penetrating into a recess 78 formed in the windowcasing 2 when the leaf 4 is in the closed position. The articulation devices herein described with reference to the drawings are simplified and serve only to provide a clearer understanding of the operation of the window. In a preferred embodiment of the invention, the pivotpins 62 and 64 are engaged in bores of the bottom cross-piece 52 of the leaf frame and the torsion bars 66 and 68 are rigidly fixed to said cross-piece 52. Similarly, the pivot-pin 76 is rigidly fixed to the top crosspiece 50 of the leaf frame.

One particularly advantageous mode of fixation of each torsion bar 66 and 68 consists in securing the free each of each torsion bar to a parallelepipedal member, each of these members being capable of sliding in a guide which is located within the interior of the crosspiece 52 and is coaxial with this latter. Moreover, by adjusting the length of each torsion bar between one of the supports andthe corresponding parallelepipedal member, the maximum opening of the window in the bellows condition is thus adjusted. Each torsion bar can advantageously be formed by means of juxtaposed torsion strips.

One possible shape of the cam 38 is shown in FIG. 6, the latch 42 having beem omitted from this figure. The contour of the cam 38 is constituted by four circular arcs, each of which subtends an angle of 90 at the centerof the shaft 40 of the cam 38. The first sector 80a is a quarter-circle which is centered on the axis of the shaft 40 and has a radius r. The second sector 80b is a quarter-circle which is also centered on the axis of the shaft 40 of the cam and has a radius R (R r). The sector 800 is a circular are which is centered at A 1 and has a radius r R. The sector 80dis a circular are which is centered'at B and has a radius r'+ R.

Moreover, the radii r and R are such that the relation between their lengths is as follows:

' and that the difference between the lengths of the radii is equal to the displacements of each rod 8 and 12. It will be readily apparent, however, that these two displacements need not necessarily be equal or in other words that the two arms of the articulation triangle 10 can very easily be of unequal length.

Since the distance between the arms 34 and 36 has the value of r R, the cam 38 is always in contact with said arms 34 and 36. The action of the cam is as follows: when the cam 38 is in contact with the arms 34 and 36 by means of the sectors 80a and 80b, the rotation of the cam 38 does not result in any displacement ofthe rod 12 since the centers of said two sectors coincide with the axis of the cam. On the contrary, when the cam 38 is in contact with the arms 34 and 36 by means of the sectors 80c and 80d, the rotation of the cam results in translational motion of the rod 12 either upwards (position I) or downwards (position II).

In an alternative form of construction which is shown in FIG. 6, the arms 34 and 36 are replaced by a slide 81 which is rigidly fixed to the rod 12. The slide 81 is pierced by a rectangular opening 81', the sides 81'a and 8l'b of which perform the same function as the arms 34 and 36.

The shape of cam which is described in this example is a preferred-form of construction but it would clearly be possible to replace this latter by a cam which has a different profile but achieves the same result without thereby departing from the scope of the invention. Over one portion of its travel, the cam must produce a displacement of the rod 12 in one direction, over another portion of travel, the cam must not cause any displacement of said rod, over a third portion, a displacement must be initiated in the other directionqln particular, it is not necessary to ensure that the angle corresponding to each circular arc should have the value of 90 in the case of each circular arc aforesaid.

In order to open the window about the axis YY' in the bellows condition, the cam is moved to the top position (position I); the rod 12 moves upwards. Under the action of the articulation triangle 10, the rod 8 moves towards the left (arrow F,)-, the elbowed portion 18 of the rod 8 frees the recess 78 of the pivot-pin 76 (articulation B). The lug 32 of the rod 12 (in the top position) engages in the groove 70 of the member 58 (articulation A), said member 58 being thus locked in position with the fixed window-casing 2. By initiating a further movement of rotation of the cam through an angle of 90 (faces 80a and 80b), the rods 8 and 12 do not move but the latch 42 withdraws into the interior of the window-casing 2. The leaf 4 can thus be displaced in pivotal motion about the axis YY.

In order to open the window about the axis X-X in the easement condition, the cam 38 is moved to the bottom position (position II). The rod 12 moves downwards and, under the action of the articulation triangle 10, the rod 8 moves towards the right (arrow F The pivot-pin 76 is therefore locked within its recess 78 (articulation B in the locked condition). Since the rod 12 is in the bottom position, the lug 32 escapes from the groove of the member 58 andpenetrates into the groove 82 which is formed in the fixed window-casing 2 (articulation A in the unlocked condition). By causing a further movement of rotation of the cam through an angle of the latch 42 withdraws. The window leaf 4 can then be displaced in pivotal motion about the axis X-X by means of the handle 83 which is attached to the window pane 48.

When the window is open, the other opening system must not be permitted toj trip as a result of accidental operation of the handle. i g i In one form of construction which is illustrated in FIG. 4,the safety device is composed of a stud 94 which is rigidly fixed to the frame upright 50 and is capable of penetrating into an orifice 96 formed in the wall of the window-casing 2, and of a pendular member 98 which is capable of swinging about a pin 100, said pin' being rigidlyfixed to the window-casing 2. When the window is closed, the stud 94 isapplied against the pendular member 98 which passes out of one of the notches 91, 91' (shown in chain-dotted lines in FIG. 2), thereby permitting displacement of the rod 8. On the contrary, when'the window is open, the member 98 is placedwithin one of the notches 91, 91 under the action of its own weight or under the action of a restoring springJThe rod 8 is thus locked -in position.

' It-is readily apparent that the window can be fitted with a safety retaining arm which is pivotally-mounted between the fixed window-casing and the leaf frame.

In one particular mode of execution, the window'can have-a woodenframe which is fixed on the windowcasing in leak-tight manner, saidwooden frame being pliedagainst thewindow flanning. At leastfour holes is rigidly fixed to the rod 8 being permitted to move within said channel. The flange 124 has an opening 130 through which the stud 128 is permitted to the window leaf 4' is closed.

' Asshown in FIG. 9,.the support-bracket 132 of the horizontal pivot-pin 114 also has a flange 134 with an are drilled insaidframe in order to attach said window to'the wall which surrounds the window flanning. This permits almost instantaneous positioning of thewindowi a In the alternative form of construction which is illustrated in FIG. 7, the' mechanism s are placed within the by means of a recess 113; Said pivot-pin cooperates with thc fork-shaped extremity 1 8' of the horizontal rod 8'. The length of said horizontal rod 8' is such that the fork-shaped extremity surrounds the pivot-pin 76' when said rod is located in the extreme right'hand position. The pivot-pin 76' is provided 'with a supportbracket 122 which is screwed onto the edge of the top cross-piece of the fixed window-casing 2'.

opening 136, a channel 137 being formed in said flange 134 and a stud 138 which is rigidly fixed to the rod 12' being permitted to move within said channel.

The operation of this alternative form of construction is as follows:

, It will first be assumed that the window is closed and that it is desired to open this latterin the bellows condition. By operating the handle, the cam 38 is caused to move the rod 12' downwardsand the rod 8' is therefore displaced towards the left-hand side of the figure. This is made possible by virtue of the fact that the studs 128 and 138 are located respectively opposite to the openings 130 and 136. The fork l8 releases the pivot 76'. Onthe contrary, the fork 116 of the rod 12 comes into engagement with the pivot-pin 114. Furthermore, the supporting member 58 is locked by means of the flat portion 120 in contact with the shoulder 118. The window can thus be opened in the bellows condition. Moreover, when the window is open any inadvertent operation of the handle is not liable to result in accidental opening of the articulation B, in fact, sincethe stud 138 is not located opposite to the opening 136,it locks the rods 8and 12 in positionf i Foropeningin the casement-window condition, the rods are brought into the position shown in FIG. 7. The

v fork 18' of the rod 8' is engaged withthe pivot-pin 76' The articulation B 'is constituted by a horizontal pivot-p'in 114 which is rigidly fixed to the window-casing 2, projects into the opening of said casing, and iscapable of penetrating into the leaf frame by means of a recess 115 formed in the wall of said frame and by means which constitutes the lower end of the whereas the fork 116 no longer surrounds the pivot-pin 114. The window leaf 4'. can then rotate about the axis X-X',.-- i

For the sake of enhanced clarity of the drawing, the pivot-pinst74' and 76' are shown in the plane of the figure. ,In actual factythe pivot-pins '76 and 74' are in a slightly forward position in order to permit opening of the window through'an angle of 180. 7 v i In FIG. 11, there is shown one example of application of the rocking-swinging window to the construction of a window-pane unit constituted by a rocking-swinging window OB and a secondary window leaf VS. The window leaf VS is capable of pivoting about the axis Z--Z' in order to open in the casement condition only when the leaf 0B is open in the casement condition. The leaf VS is fitted with anespagnolette or casement bolt 140, the lower end of which is capable of engaging within the aperture 142 formed in the casing 144 of the windew-pane unit. The casement bolt has a lug 146 which is engaged in the slot l48.of the member 150,

said member being capable of sliding with respect-to the rod 12'. Said member 150 also has two arms 152 1 and 154 and these latter surround. the cam 156 which is identical in shape with the cam 38' described earlier. The two cams are coupled in their movement of rotation about the spindle 40': they are set at an angle of 90 with respect to each other. The pivot-pin 1 14 is rigidly fixed to the frame 158 of the leaf VS. There is also shown a safety system constituted by a blade spring 160 pass when shown by the arrow fl), the window leaf OB can be opened in the casement condition since the latch is withdrawn. The movement of rotation of the'cam 154 causes the upward displacement of the member 150 which is accompanied in its movement by the espag- .nolette or casement bolt 140. The window leaf VS can accordingly be opened in the easement condition. On the contrary, if the handle is rotated through an angle of 90 in the downward direction (arrow f2), the rod 12' moves downwards under the action of the cam 38 and the latch withdraws. The leaf OB can accordingly be opened in the bellows condition. The movement of rotation of the cam 156 leaves the member 150 in a stationary position. The window leaf VS remains closed. The safety system consisting of the blade spring 160 has the sole object of preventing re-closure of the leaf OB when the leaf VS is open. This is necessary by reason of the fact that, when the leaf VS is open and the leaf OB is closed again, safety of the articulation point B no longer exists.

The advantage of this device lies in the fact that a rocking-swinging window and a leaf which opens in the easement condition can be placed in juxtaposed relation without interposition of a mullion.

It is readily apparent that the invention is not limited to the particular form of construction of a window- -pane unit as hereinbefore described but also extends to all equivalent mechanical means which serve to obtain the same movement of the casement-bolt 140, starting from the movement of the rod 12 or of the cam 38.

. One advantage of the window in accordance with the inventionlies in the fact that the movements of the cam ,areirreversible. In fact, taking into account the shape of said cam, if the window is subjected to violent vibrations orto an impact, those portions of the cam profile which are in contact with the arms 34 and 36 remain the same. Anyunforeseen pivotal motionof the cam' 38 and consequent opening of the window cannot take place under such conditions. i

The same advantage would not again be found if the cam 38 were replaced by an-eccentric. However, it

would clearly not constitute any departure from the scope of the invention if provision were made for an ec-v centric instead of a cam since this latter represents only one particular form of construction.

A' further advantage of the window lies in the extreme simplicity of the casing since thislatter is provided only with a slot for the introduction of the latch which is rigidly fixed to the cam, and the holes for fixing the supporting members 122 and 132. Moreover, the choice of construction of the vertical hinge unit v permits very easy positioning of the leaf within the window-casing.
